Was your math level when graduating high school calculus or higher?
Calculus wasn't offered at my high school when I graduated due to a change in math systems/textbooks & a HORRIBLE math teacher who was only there for my sophomore year & left basically everyone needing to retake the math they took with him, because even those with A's had no idea how to do what they were supposed to do!
I was math handicapped, so pre calc is the highest I took in high school. Didn't do so well in it either...
I took calculus my sophomore year. That was only because I was in an advanced program that allowed me to double up math in my freshman year. I took algebra 2 and precal.
I had a year of calculus in high school, which was almost unheard of then (at least at my highly rated school, so I imagine in most places). I'd been put ahead a year in math only, along with 3 others, in an experimental math program starting in 9th grade (when we were still in 8th). That meant there were 4 of us who had completed all 4 years of math, going into our senior year, so they gave the 4 of us a year of calculus.
I'll be taking AP calc my senior year.
